  Abstract


Spent pickle liquor (SPL) of electroplating industry is a major source of hazardous industrial wastes. Various methods have been investigated for the recovery of acid(s), Hydrochloric acid and Sulfuric acid from SPL. Each has got its own merits and demerits. Solvent extraction is one of the method used for recovery of inorganic acids from wastewater. Extraction of hydrochloric acid and sulfuric acid by solvents was studied from spent pickle liquor containing 92 g/l hydrochloric acid and 491g/l sulfuric acid . Recovery of all two acids increased with the increasing concentration of the solvents. For all the solvents studied, the species extracted into the organic phase appears to be associated with nearly one mole of solvent. The acids extracted by Aliquat 336 and Tributyl phosphate (TBP) were easily stripped with water. But sulfuric acid extracted with Alamine 336 was not stripped with water. The stripping efficiency was ?11% with dilute sulfuric acid and increased with 0.1 N NaOH for acid loaded onto Alamine 336.
